DESCRIPTION
The STE2001 is a low power CMOS LCD controller driver. Designed to drive a 65 rows by 128 columns graphic display, provides all necessary functions in a single chip, including on-chip LCD supply and bias voltages generators, resulting in a minimum of externals components and in a very low power consumption. The STE2001 features three standard interfaces (Serial, parallel, I2C) for ease of interfacing with the host µcontroller.
â 65 x 128 bits Display Data RAM
â Configurable matrix: 65 x 128 or 33 x 128
â Programmable (65/33) MUX rate
â Row by Row Scrolling
â Automatic data RAM Blanking procedure
â Selectable Input Interface:
⢠I2C Bus Fast and Hs-mode (read and write)
⢠Parallel Interface (write only)
⢠Serial Interface (write only)
â Fully Integrated Oscillator requires no external components
â Fully Integrated Configurable LCD bias voltages generator with:
⢠Selectable (5X, 4X, 3X, 2X) multiplication factor
⢠Effective sensing for High Precision Output
⢠Four selectable temperature compensation coefficients
â Designed for chip-on-glass (COG) applications
